STEEL PIPE PILE WITH SPIRAL BLADE, PILE CONSTRUCTION METHOD, AND BUILDING
PROBLEM TO BE SOLVED: To provide a steel pipe pile with a spiral blade, with which a lower reinforcing plate and an upper reinforcing plate work together to attain a reinforcing effect against bending moment exerted on a steel pipe tip from the spiral blade disposed on an outer peripheral surface of the steel pipe tip.SOLUTION: The present invention relates to a steel pipe pile 1 with a spiral blade having a spirally continuing spiral blade 5 disposed on an outer peripheral surface 2a of a steel pipe tip 2. The steel pipe pile 1 with a spiral blade that applies the present invention includes a lower reinforcing plate 3 provided in an inner part 20 of the steel pipe tip 2 at a lower side in a pipe axial direction Y, and an upper reinforcing plate 4 provided in the inner part 20 of the steel pipe tip 2 at an upper side in the pipe axial direction Y. The lower reinforcing plate 3 is provided on a steel pipe cross-section A below a tip part 5a at a bottom edge of the spiral blade 5, while the upper reinforcing plate 4 is disposed on the steel pipe cross-section A above a position Pu reached by spiraling once around the outer peripheral surface of the steel pipe tip from the tip part 5a at the bottom edge of the spiral blade 5.SELECTED DRAWING: Figure 4
【課題】鋼管先端の外周面に設けられた螺旋翼から鋼管先端に作用する曲げモーメントに対して、下部補強板と上部補強板とが相俟って補強効果を発揮することのできる螺旋翼付鋼管杭を提供する。【解決手段】略螺旋状に連続する螺旋翼５が鋼管先端２の外周面２ａに設けられた螺旋翼付鋼管杭１に関する。本発明を適用した螺旋翼付鋼管杭１は、鋼管先端２の内部２０で管軸方向Ｙの下側に設けられた下部補強板３と、鋼管先端２の内部２０で管軸方向Ｙの上側に設けられた上部補強板４とを備える。下部補強板３は、螺旋翼５の下端先端部５ａより下方の鋼管断面Ａに配置されて、また、上部補強板４は、螺旋翼５の下端先端部５ａから鋼管先端の外周面でひと巻きした位置Ｐｕより上方の鋼管断面Ａに配置される。【選択図】図４
